Installation
Attaching to the Tractor
The 500 litre Oktopus sprayer is equipped to fit
tractors with either Category I or II linkage
systems. The inner end of each lower linkage
pin is Category I diameter and the outer end is
Category II. The lower holes in the top
connection plates are Category I diameter and
the upper holes are Category II. For best
stability install the lower linkage pin with the
end which is to be used to the outside.
Remove the PTO shaft from the sprayer by
depressing the locking pin. Lower the tractor
linkage and attach to the sprayer’s lower hitch
pins of the appropriate category, then connect
the upper linkage arm using
the tractor’s link
pin. Secure all link pins with
the tractor’s linch
pins. Raise the tractor linkage to the desired
spraying height and level the sprayer by
adjusting the length of the top linkage arm.
Clean and grease the splines on the tractor
and sprayer PTO stub shafts and install the
PTO shaft making sure that the spring-loaded
locking pins engage in the grooves of both
stub shafts. Ensure that the tractor’s PTO shaft
guard is attached to the tractor.
PTO Shaft Length
Note: Upon delivery of a new sprayer it is the
selling dealer’s responsibility to install and set
the PTO shaft to the correct length. The
following information is provided for reference.
Set the linkage height so the ends of the two
drive shafts are at their closest. Install the PTO
shaft making sure there is at least 25mm of
telescopic travel remaining between the male
and female sections. Raise and lower the
sprayer to check that the PTO telescopic tubes
overlap by approximately 1/3rd their length,
and not less than 150mm, in all operating
positions. See fig.2
If the PTO shaft must be shortened cut equal
amounts from both male and female shafts
and safety covers. Carefully remove all burrs
then
clean
and
relubricate
before
reassembling.
Cabin Mounted Control Box
Connect the electrical cables provided for the
switch box directly to the battery.
Positive =
Red
Negative = Black
If the cable needs to be extended it is
important to use wire of the same diameter.
These cables supply power to the electric
valves.
If an automatic rate controller is used refer to
appropriate installation manuals.
Run the controller wiring loom back to the
sprayer through a convenient outlet in the
tractor cabin, ensuring that it does not rub on
any sharp edge. Connect the tractor loom to
the sprayer loom at the quick release coupling
and ensure that all wiring is clear of the PTO
shaft and tractor wheels.
